Understanding Balanced Ventilation
is proud to serve San Antonio and the neighboring communities. Evaluating and optimizing home ventilation is an important part of what we do. After all, the EPA warns that poor indoor air quality is among the most serious health risks Americans face. Balanced ventilation is an approach to ensure that the air inside a house is never more polluted than the air outside it. Airflow Within a Home You have two primary types of ventilation within a home: natural and mechanical. When you open a window to let in fresh air, that is an example of natural ventilation. Modern houses are well-sealed, so they tend to get little natural ventilation when the heating or cooling systems are running. Mechanical ventilation is achieved through intakes, ductwork, and exhausts. Traditional Ventilation The traditional ventilation used in homes is supply ventilation. Air enters the house through a passive duct, which means the intake occurs as it is needed. In a central system, conditioned air is moved through the home using ductwork. A passive duct replenishes the air as the pressure drops. Balanced Ventilation Balanced ventilation is a newer approach, and the traditional ventilation discussed above is sometimes called unbalanced ventilation. In a balanced...
